There are primarily two profiles of press fittings that are M profile and V profile. Both of these profiles are 90% the same to each other and provide the same level of efficiency and effectiveness. There are no technical differences that have been figured out as yet; neither are there any quality or result-driven differences. When the plumbing professionals are asked about their preference, they usually choose the profile as a matter of their habit. The professional who is used to utilizing the M profile is least likely to switch to the V profile.
How the quality of press fittings are mandated?
Several quality-related amendments, as well as improvements, are made to the press-fittings technology. The raw materials of this equipment are made better from the best. We know that the press fittings used to be made using metal, raw copper, and aluminum. Later on, the use of stainless steel was incorporated to eliminate the issues that have been identified while using copper. There were certain quality as well as health-related issues that needed to be catered appropriately. Stainless steel performed an excellent job. Recently we have been seeing the modern profiles being made using lead-free raw material, thus, mandating the quality and safety to the 100%
The requirement of certifications to mandate the quality
Several certifications are required in order to ensure that guaranteed that the quality and high standards are met. The certified profiles are mostly preferred by plumbing professionals. So far, the best known certified patterns are the DVGW press fittings. They are known to be of high standards and optimized quality. Other standardized certifications include the ISO9001, WARS, watermarks, OVGW, and VA, respectively. Press fittings are most widely used, and their quality optimization while mandating the quality control and assurance is very significant.
